I well remember Davydenko losing to a certified, CAUGHT doper in the 2005 semifinal of RG. If I'm not mistaken said Doper got an immediate ban and his name/points were scratched from the ultimate results list/ATP rankings (correct me if I'm wrong here).
Unfortunately it didn't bring Davydenko any of the deserved accolades, as it should have been HIM playing the RG final against Nadal that year - perhaps never mind, as he probably would have lost anyway, but still it leaves a bad taste in my mouth.
Isn't Davy also a cheater though? Like with match fixing?
